Wall and floor tile used for interior and exterior decoration belongs to a class of ceramics known as whitewares. The production of tile dates back to ancient times and peoples‚ including the Egyptians‚ the Babylonians‚ and the Assyrians. For instance‚ the Step Pyramid for the Pharoah Djoser‚ built in ancient Egypt around 2600 B.C. ‚ contained colorful glazed tile. Later‚ ceramic tile was manufactured in virtually every major European country and in the United States. By the beginning of the twentieth

obtain the precipitate. The crucible used to contain the precipitate is porcelain and unreactive‚ so that it will not react with the precipitate and affect the accuracy of the experiment. It is also resistant to high heat‚ making it convenient for drying using an oven‚ effectively ridding all water content‚ so that an accurate mass of the precipitate can be measured.

the crucibles were washed to remove any other adhering compounds. Then‚ they were dried by being put inside an oven at a temperature slightly above the boiling point of water‚ 110ºC. Other methods for drying are available such as infrared drying‚ halogen drying and microwave drying‚ but the drying oven was used because it is the most accessible‚ and multiple samples can be determined at once. The weights were then measured after letting the crucibles dry and cool in a desiccator. Multiple weighings
